Notes: ω-Agatoxin IVA is a natural peptide first isolated from the venom of funnel spiders.{33629} It selectively and irreversibly blocks P-type calcium channels (IC50 <1 nM), high voltage-activated channels first discovered in Purkinje cells.{33630,33632} ω-Agatoxin IVA also blocks N-type calcium channels at micromolar concentrations.{33632}
